Iris IV

K: Dmaj (incorporating Bmin, Lydian) T: 50 TS: 3/4 INST: Piano, Viola/Cello, Strings, Synth Pad/Choir, Harp/Dulcimer Mood: Ambient, melancholic, peaceful, celestial, tranquil, solitary Structure: Through-composed (Intro, Middle Development, Ambient Expansion, Fading Resolution) This piece is described as a slow, atmospheric, and emotive instrumental work inspired by Jeremy Soule's "Secunda". It features a very slow tempo (48-60 BPM) in a 3/4 time signature, giving it a gentle, flowing character. The key centers around D major but incorporates modal shifts to B minor and Lydian, utilizing simple, emotive chord progressions, suspensions, and pedal tones to create a sense of longing and ambiguity. The instrumentation is sparse, primarily featuring solo piano, muted strings (viola/cello, tremolo strings), and soft synth pads or choir textures, all played with soft dynamics, legato phrasing, and significant sustain/reverb. The structure is through-composed, eschewing strict repetition in favor of slow, organic evolution through distinct sections (Intro, Middle Development, Ambient Expansion, Fading Resolution). The overall style is deeply ambient and introspective, aiming to evoke a sense of peaceful nightfall, gentle melancholy, and solitary stargazing through subtle dynamics, sparse textures, and harmonic warmth.
